Why Am I Getting 'No Suitable Driver Found' when Connecting to MySQL in Java?

SQLException: No Suitable Driver Found

Issue

When attempting to establish a connection to a MySQL database in a Java code, users may encounter a "No suitable driver found" error. This occurs despite verifying the presence of necessary JAR files and restarting the Tomcat server.

Solution

The possible causes for this error are:

1. JDBC Driver Not Loaded: Ensure that the JDBC driver is correctly loaded.
2. Incorrect URL: Verify that the URL used for database connection matches the correct format: jdbc:mysql://localhost:3306/dbname.

Troubleshooting Tips

• Double-check the inclusion of the correct JDBC driver JAR files in the WEB-INF/lib directory.
• Examine the URL used for connecting to the database to ensure it matches the expected format.
• Consider separating Java code from JSP files to improve code organization and prevent execution issues.
• Enhance exception handling by throwing exceptions instead of merely printing error messages, ensuring proper error propagation.
